STOVE-Pl PE TH l MBLE.

SPECIFICATION forming part of Letters Patent No. 307,887, dated November11, 1884.

Application filed February 23, 1884.

To all whom it may concern.-

Be it known that I, JAMES L. WILBER, of Farmington, in the county ofOakland and State of Michigan, have invented new and useful Improvementsin Stove-Pipe Thimbles; and I do hereby declare that the following is afull, clear, and exact description thereof, reference being had to theaccompanying drawings, which form a part of this specification.

This invention relates to certain new and useful improvements in theconstruction of stove-pipe thimbles of that class which are designed tobe placed in floors and ceilings.

The invention consists in the peculiar manner of securing the bands tothe heads, by means of which no soldering is required; also in the meansemployed to secure the parts together so that one band attached to oneof the heads may be detached from the other head to which the other bandis attached, the more readily to get at and clean the interior whennecessary; also, in the peculiar construction of the parts and theircombination, as more fully hereinafter described.

Figure 1 shows the two bands and heads detached and in perspectiveelevation. Fig. 2 is a section showing the manner in which the bands aresecured each to its head. Fig. 3 is another section showing the mannerin which the two parts are detachably secured together, each partconsisting of a head and band.

In the accompanying drawings, which form a part of this specification, Arepresents one head, and B represents theoutside shell or band. Thisband is preferably made of tin, and of any desired length to suitcircumstances. The head A is preferably made of cast-iron with twoseries of holes in a larger and smaller circle, as shown, the two seriesof such holes being separated by a ring, a, and the outsidecircumference of the head being another ring, b. The outside band, B, isa little smaller in circumference than the outer circumference of thering b,which rests on the end of the band, and is secured thereto bymeans of the metallic straps 0, which embrace the ring I) or a portionthereof, and the free ends of these straps pass along the outerand-inner'wall of the band, and are secured thereto by rivet or rivetsd, passing through the straps and wall of the band. The inner band, 0,is smaller than the outer band, and is secured toits head D by means (Nomodel.)

of similar straps, which engage with the ring which divides the twoseries of holes in the head in the same manner as above described. Thetwo bands are now respectively secured each to its own head withoutsoldering. The smaller band is now inserted within thelarger one, and,both being of the same length, the device will be presented asconsisting of two cylinders with open heads so arranged that there willbe an air-space between them communicating at each end with the outerair through the outer series of holes in the heads. When in position aslast described, it becomes necessary to fasten the two sectionstogether. This I do by securing one or more leaf-springs e to the inner,wall of the outer band, so that they project beyond its end sufficientlyfar to engage with the outer ring of the opposite head through the holestherein. By this or equivalent means I am able to so connect the twosections together that they may be separated at pleasure when it isdesired to clean the inside of the bands from the accumulated dust. The,inner series of holes, which may be partially broken out, if desired,allow communication with the. outside air with the air-space surroundingthe stove-pipe and between it and the inner band, the walls of the innerseries of holes forming a rest to support the stovepipe centrally in thedevice.

I am aware of the Patents Nos. 199,423 and 279,205, and make no claim tothe construction shown therein as forming a part of my invention.

WVhat I claim as my invention, and desire to secure by Letters Patent,is-

1. The band B, having secured thereto the metal head A by means of themetallic loops 0, which pass through holes in said head, and the freeends of which pass along the inner and outer wall of said band and aresecured thereto by rivets, substantially as described.

2. A stove-pipe thimble consisting of two independent sections each ofwhich is composed of a band and cast-metal head, the outer .of suchbands being provided with springs riveted to its walls, and adapted toengage with holes in the head of the smaller band, substantially as setforth.
